I already posted on your other thread
, I wouldn't enter University unless you're absolutely certain or at least 80-90% confident in what you want to study otherwise it's just going to be trainwreck on top of having SA. It'll be difficult for you to cope unless you have clarity and know exactly what you want.
You might feel more alone too and become more depressed because you're going to be confronted with people who aren't lonely, who don't have SA and who know what they want in life, and will get it. I would suggest against studying unless you're really passionate about what you want to do and have a clear vision in that.
Go to Uni/tert education when you're ready, when you have more clarity and can cope more with SA and being alone.
Depending on your economic status, it can be a big mistake to enroll too early into something you're not even sure about. It is your choice though, if your family is loaded then the blow won't be as big if you don't succeed but you would've have still used up valuable years of your life. That's why I suggest going when your heads in the right place first or at least when there's less clutter and more focus. :/
If I was about to enter Uni/Tert, I'd be worried about being the most talented or skilled in my field than being alone. :P
